core: unmap overlay window when we first acquire it
It used to be unmap when we receive its MapNotify, but now since we discard
events received before we grab X server, that event it lost. But it
turns out we can just unmap it when it's first created, no need to wait
for the MapNotify.

Partially fix #160

Remove several unnecessary experimental_backends check
Window flags can be set whichever backend we use, we will ignore then in
paint_preprocess. free_paint can be called whichever backend we use,
they just do nothing if we use experimental backends.

Others should rather just check if backend_data is NULL.

Making the code slightly more understandable, also making the eventual
removal of these checks easier.

core: mark newly created window as damaged
Damage could have already happened at the time we call fill_win on a new
window. It's too difficult, or impossible, for us the find out if that
happened. So just blindly mark window as damaged.

x: add x_discard_events
Also, during session_init, discard old events after we grab the server.
If we don't do that, old, out dated CreateNotify will cause us to add
the window with the same id multiple times. Here is an explanation of
how that could happen:

1. compton connects to X
2. a new window created by someone else, X send us a CreateNotify
3. compton is initializing, so it didn't handle the event.
4. compton pulls a list of all windows from X. This will include that
   window created in (2)
5. compton starts to handle event. it will handle the CreateNotify sent
   in (2), thus adds the same window twice.

win: fix add_win_top
Instead of reusing add_win_above with the id of the window on the top
of the stack, we create a new function that takes a list_node.

Fix a problem when the window on the top of the stack is destroyed. Because
add_win_above search for windows from the hash table, it won't find that window
and returns NULL.

win: split struct win
Currently compton handles window creation event by immediately query all
the information it needs and create a window struct with that
information. However, this is prone to race conditions.

In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.

This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.
